Slope and curvature of the hadron vacuum polarization at vanishing virtuality from lattice QCD
Sz. Borsanyi, Z. Fodor, T. Kawanai +7
We compute the slope and curvature, at vanishing four-momentum transfer squared, of the leading order hadron vacuum polarization function, using lattice QCD. Calculations are perfo…
Treatment of overlapping gaseous absorption with the correlated-k method in hot Jupiter and brown dwarf atmosphere models
David S. Amundsen, Pascal Tremblin, James Manners +2
The correlated-k method is frequently used to speed up radiation calculations in both one-dimensional and three-dimensional atmosphere models. An inherent difficulty with this meth…
The UK Met Office GCM with a sophisticated radiation scheme applied to the hot Jupiter HD 209458b
David S. Amundsen, Nathan J. Mayne, Isabelle Baraffe +6
To study the complexity of hot Jupiter atmospheres revealed by observations of increasing quality, we have adapted the UK Met Office global circulation model (GCM), the Unified Mod…
Sharpening methods for finite volume schemes
B Després, S Kokh, Frédéric Lagoutière
We review sharpening methods for finite volume schemes, with an emphasis on the basic structure of sharpening methods. It covers high order methods and non linear techniques for li…
A hierarchy of simple hyperbolic two-fluid models for bubbly flows
Florence Drui, Adam Larat, Samuel Kokh +1
With the objective of modeling both separate and disperse two-phase flows, we use in this paper a methodology for deriving two-fluid models that do not assume any flow topology. Th…
Feedback in Clouds II: UV Photoionisation and the first supernova in a massive cloud
Sam Geen, Patrick Hennebelle, Pascal Tremblin +1
Molecular cloud structure is regulated by stellar feedback in various forms. Two of the most important feedback processes are UV photoionisation and supernovae from massive stars.…
